What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I think your product is fabulous and quite easy to use. My problem is that I have a very part time office and paying the monthly or even yearly subscription is difficult. A per use charge might work better for me.

All of my forms have looked super professional, and when I applied for my new job, the HR department thought it was going the extra mile to type out my application instead of handwriting it.
2015-05-18
No way to easily add additional pages in a template I used. Had to keep erasing everything to start new page. “Next” button skips all over the page, so this isn’t tablet-friendly. Waste of my annual subscription fee.

I'm a noob when it comes to computers, but this app helps me and I have been able to complete the court doc's I need to get $ back from my Ex. That's something I would not have been able to do without PDFfiller. Awesome app. David B Roseville Ca

I'm learning how to use the program. We need it for online school for our granddaughter
It is a bit complicated. As we learn to print and save and figure out which document it which, it will be easier to use
2019-11-13
I needed this program badly, just in the time for distance learning because of the Corona Virus. It was easy to navigate through and use. My only wish is that I would have found this program years earlier! I will update my rating to include the student (recipient) experience of pdfFiller after they return their first homework assignment.

Billing, invoices and subscription
Kara was excellent help in clarifying payment and free trial with me. Very friendly and helped solve the issue in seconds. Conclusion, the invoice can only be downloaded after the free trial has ended and subscription actively kicks in.

i enjoyed typing up the form i needed…
i enjoyed typing up the form i needed with pdffiller it really helped me create the form that i needed. the only thing wrong with it was not having spell check. thanks again
2021-11-24
*** ****** is literally the best *** Filling *** out there. ******. All the functionalities of *** filler are remarkable and make doing business a complete breeze. Unfortunately the Platform I use daily - is cheaper however - isnt as functional as *** filler. So I tried completing my need with them as I have used them in the past. So I signed up for the trial - attempted my documents - I failed; closed the window and forgot about the subscription. This morning I woke up and saw the charge, I couldnt remember what Email I even signed up with. I emailed *** ****** at 5 am and got an immediate response with an agent ready to help. They asked easy questions and were able to locate my account and issue an immediate refund. I dont think there are words to express how incredible and unmatched that level of customer service is. Thank you *** ******

What is refractive index formula?
Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. ... Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v.
What is refractive index with example?
It is defined as. where c is the speed of light in vacuum and v is the phase velocity of light in the medium. For example, the refractive index of water is 1.333, meaning that light travels 1.333 times as fast in vacuum as in water.
What is refractive index?
Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. ... Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v.
How do you calculate refractive index?
Determine the speed of light in the analyzed medium. ...
Divide the speed of light by this value. ...
The obtained value is the refractive index of the medium.
You can use this value to calculate the angle of refraction, using our Snell's law calculator.
What is the difference between refraction and refractive index?
What is the difference between refraction and refractive index? ... In Optics, refraction is a phenomenon that often occurs when waves travel from an optically less/more dense medium of a given refractive index to an optically more/less dense medium with another refractive index at an oblique angle.
What is the formula of refraction?
When scientists talk about refraction, they use a formula. “N = c / v” “c” is the speed of light in a vacuum, “v” is the speed of light in that substance and “n” is the index of refraction.
What is the formula of Snell's Law?
The formula that describes refraction is also known as Snell's Law. ... Snell's Law Formula Questions: 1) A beam of light in air makes an angle of 41.8° relative to the normal to the surface of a pool of clear water. The index of refraction for air is 1.000, and the index of refraction for the water is 1.333.
What is Snell's law of refraction of light?
Snell's law (also known as Snell-Descartes law and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air.
What are the 2 laws of refraction of light?
Laws of Refraction. ... Laws of refraction state that: The incident ray, reflected ray and the normal, to the interface of any two given mediums; all lie in the same plane. The ratio of the sine of the angle of incidence and sine of the angle of refraction is constant.
What is the formula for relative refractive index?
Then we can find the relative refractive index 1n2 by dividing the speed of light in material 1 (c1) by the speed of light in material 2 (c2) OR by dividing the refractive index of material 2 (n2) by the refractive index of material 1 (n1) OR by dividing the sine of the incident angle (q1) by the sine of the refracted ...
